5.2.1 Sensor Head Cable

The manufacturer preinstall’s the sensor head cable between sensor head and electronic box. It may be shortened but not lengthened.

Shortening the cable length by 1 m (3 ft.) causes a temperature error of – 0.1 K / m!

Do not bend the sensor head cable tighter than 25 mm / 1 in. (MID/MIC) and 15 mm / 0.6 in. (MIH) respectively!
